2 Claims.

This invention relates to improvements in a suction cleaner, of theso-called vacuum cleaner type, and appertains particularly to the dustreceiving bag.

An object of the invention is to provide an improved bag, to receive theout-put from a conventional motor-driven unit, that will thoroughlyremove the solids and purify and disinfect the air passing therethrough.

A further object of the invention is to provide a bag of materialimpervious to air, having an inlet, for attachment to the motorizedunit, and an outlet and between which inlet and outlet the air passesfirst through a dust extracting bag and then one or more filters forpurifying and disinfecting the air.

A further object of the invention is to provide a bag-like attachmentfor use with a suction cleaner adapted to purify and disinfect the airout-put and having an outlet designed to removably receive a tubularconduit or other accessory.

A still further object of the invention is the provision of a bag for asuction cleaner, of the nature and for the purposes described,characterized by structural simplicity, durability, efficiency and lowcost of production, being thereby rendered commercially desirable.

To the accomplishment of these and related objects as shall becomeapparent as the description proceeds, the invention resides in theconstruction, combination and arrangement of parts as shall behereinafter more fully described, illustrated in the accompanyingdrawing and pointed out in the claims hereunto appended.

The invention will be best understood and can be more clearly describedwhen reference is had to the drawing forming a part of this disclosure,wherein like characters indicate like parts throughout the severalviews.

In the drawing- Figure 1 is a sectional elevation of the improved bagattached to a conventional suction cleaner;

Figure 2 is an enlarged section of a means of attaching a conduitto theoutlet of the bag;

Figure 3 is a detail elevation of the coupling there used;

Figure 4 is a side elevation, partly in section, of the connection ofthe bag with the motorized unit;

Figure 5 is a perspective elevation of a modified form of air cleaningattachment, being, of rubberized fabric with a separable fastener at itsfree end; and

fine particles of the dust continually blocking the pores of the bagreduce its efficiency, yet nevertheless gradually emanate therefrom'thusscattering dirt and germs about the house.

The present device, adapted to be used as an air-cleaning replacementfor bags of the type in current use, provides first an effectivedustremoving bag and then a. subsequent filtering and disinfecting ofthe air passed by the bag. This air-cleaner comprises a jacket or casingI having an outlet opening 2, adapted for removable attachment asdesired to the out-put 3 of a conventional motorized suction cleanerunit 4, and an outlet opening 5, such for instance as that shown at theupper end and rounded to deliver downwardly. Within this jacket, whichpreferably is formed in two parts so that the upper end la; may be takenofi, there is an airpassing dust-collecting bag 6, confined in the lowerpart in a reticulated wire cage 1 spaced from the inner wall of thecasing, having its open mouth 8 concentric with and removably secured inthe inlet 2, as by the wire clamping ring 9.

In the upper part of the casing l, i. e., between the dust collectingbag 6 and the outlet 5, the air purifying filters ID are interposed. Anydesired number may be used and these may be impregnated with deodorant,disinfectant or other selected substance to treat or purify the passingflow of air. These filters I0 are shown as held between a fixed screen Hand removable spacing screens I2, the last of which is confined by theinterior flange I3 on the lower part of the casing I at the juncturetherewith of the removable upper portion la.

As the stream of chemically treated air delivered at the outlet 5 issusceptible of various uses, as for instance disinfecting sick rooms,moth proofing cupboards, drawers, etc., the outlet 5 may be formed as anozzle to receive a hose or conduit l4 that is removably attachedthereto in any preferred or desired manner as by the spring urged studIE on the conduit ferrule 16 and the cooperating indentation I! on thenozzle end 5.

A further adaptation of this invention is shown in Figures 5 and 6 wherethe air impervious casing I is of rubberized fabric with a reinforcedinlet opening 2', adapted for attachment to a suction cleaner in theusual way, and an opening it, preferably at the opposite end. normallysealed with a separable fastener I8 and a non-closable air outlet 5 ator near this zipper-closed free end. In this modification, theremovable, ioraminous. dust-extracting bag 6' has its mouth in theintake 2' while beyond the inner end of the bag a filter I0 is held, asby dome fasteners, not shown, between a pair of adjacent interior foldsor tucks 20.

In this simplified embodiment, the outer Jacket or casing l' is muchsmaller than that shown in the rigid bag I in Figure 1. Access to thefilter I0 is aflorded by way of the zipper-closed opening it, throughwhich the dust bag 6' may also be removed if the inlet opening I be toosmall or otherwise inconvenient.

From the foregoing description taken in connection with the accompanyingdrawing, it will be manifest that a suction cleaner bag is provided thatwill fulfil all the necessary requirements of such a device but as manychanges could be made in the above description and many apparentlywidely different embodiments of the invention may be constructed withinthe scope of the appended claims without departing from the spirit orscope thereof, it is intended that all matters contained in the saidaccompanying specification and drawing shall be interpreted asillustrative and not in a limitative or restrictive sense.

Having thus described my invention. what I claim as new and desire tosecure by Letters Patent is:

1. A bag for a suction cleaner, comprising a jacket of materialimpervious to air having an inlet opening adapted for attachment to theout-put of said suction cleaner unit and an outlet nozzle at or near theremote end, a dustcollecting sack with its mouth arranged in said inletopening. and at least one filter pad removablycarrled by said jacket,said Pad separating said outlet nozzle end from the rest of the jacketso that air passed by said dust-collecting sack must filter through saidpad before finding egress from said outlet home.

2. A bag for a suction cleaner adapted for attachment to the out-putport of a suction cleaner and comprising a jacket of material imperviousto air, an inlet therefor attachable to the output of said cleaner, adust-collecting sack with an open mouth located in said inlet, an outletnozzle near the free end of said bag and a replaceable filter dividingsaid jacket between said dustcollecting sack and said outlet nozzle.
